Both the Pursuit OS 375 2010 and the Pursuit S 310 2009 are deep-V designs, both built in fibreglass, so the buying decision usually comes down to a handful of practical questions: how many people are you putting on the water, how far do you trailer, and what does your tow vehicle weigh?

Size is the most obvious dividing line here. The Pursuit OS 375 2010 measures 39,2 feet overall (2010), giving it roughly 8,0 additional feet of deck space compared to the Pursuit S 310 2009 at 31,2 feet (2009). Weight tells a clearer story for trailering families: the Pursuit OS 375 2010 tips the scales at 18 985 lbs - 10 112 lbs more than the Pursuit S 310 2009 at 8 873 lbs. That difference is meaningful if you're working within a half-ton or three-quarter-ton truck's tow rating, especially once you factor in a motor, gear, and fuel.

The power gap is worth calling out. Rated to 1 050 hp, the Pursuit OS 375 2010 has a 550-hp advantage over the Pursuit S 310 2009's 500-hp ceiling - enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Fuel capacity breaks the other way: the Pursuit OS 375 2010 carries 370 gallons versus 260 gallons in the Pursuit S 310 2009. On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.

For family outings this is probably the sharpest distinction between the two. The Pursuit OS 375 2010 is rated for 11 passengers, while the Pursuit S 310 2009 caps at 9. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Pursuit OS 375 2010 could be the deciding factor.
